The Different Types of Cannabis Plants

Although cannabis is often thought of as a single plant species, it is actually comprised of two different types of plants: male and female. Both types are necessary for the plant to reproduce, but only the female plant produces the flowers that contain the THC-laden resin that is used to make marijuana. So, how can you tell the difference between a male and female cannabis plant?

Male Cannabis Plants

Male cannabis plants are easy to spot, and they can ruin your entire crop if you’re not careful. Here’s how to identify them so you can get rid of them before they cause any damage.

Male cannabis plants are taller and thinner than female plants, and they have much smaller flowers. The flowers are also spaced further apart on the stem. Male plants also don’t produce nearly as much resin as female plants.

If you’re growing cannabis for personal use, you probably won’t want any male plants in your grow space. That’s because they don’t produce buds, which is what you’re after when you grow cannabis. Male plants are only good for breeding or if you want to make your own seeds.

If you do find male plants in your grow space, the best thing to do is to get rid of them right away. You can either pull them up by the roots or cut off the flowers so they can’t spread their pollen.

Female Cannabis Plants

Female plants are the only ones that produce buds, the part of the plant that is typically smoked, vaporized, or used to make edibles or concentrates. Each strain has its own unique cannabinoid profile, so female plants of different strains will have different effects when consumed.

To ensure your female plants stay healthy and produce lots of buds, it’s important to give them the right environment and nutrients. Once you have your grow space set up and your plants have been properly fertilized, you’ll need to pay close attention to them to make sure they are getting the right amount of light and water.

Hermaphrodite Cannabis Plants

Hermaphrodite cannabis plants are those that have both male and female characteristics. These plants typically have both staminate and pistillate flowers on the same plant. This can occur naturally, or it may be the result of stress from environmental factors such as extreme heat or cold, malnutrition, or damage to the plant. Hermaphrodites are often considered undesirable by growers because they can pollinate themselves and other nearby female plants, resulting in seeded buds. However, some growers believe that hermaphrodites can produce higher-quality buds due to the increased amount of resin produced by these plants.

How to Identify Male Cannabis Plants

Male cannabis plants can be difficult to identify, especially if you’re a beginner grower. However, there are a few key differences that you can look for. Male plants tend to be taller and thinner than female plants. They also tend to have fewer leaves. The flowers on male plants are also much smaller. If you’re still not sure, you can always ask a dispensary or grower for help.

Look for Pre-flowers

The most common and reliable way to determine the sex of a cannabis plant is to look for pre-flowers, which begin to develop about 6-8 weeks into the plant’s life cycle. Male plants will produce small, round flowers that grow in clusters, while female plants will develop fatter, more tear-shaped flowers.

To make matters more complicated, some hermaphrodite plants (plants that are both male and female) will also develop pre-flowers. However, these flowers will usually have characteristics of both sexes (for example, they may be slender like female flowers but have pollen like male flowers).

If you’re still not sure which plant is which after examining the pre-flowers, you can always wait until the plant produces actual flowers. Male cannabis plants will produce pollen, which can be seen as small yellow or white sacs. Female plants will not produce pollen, but they will develop white hairs called pistils.

Check the Shape of the Flowers

Once cannabis plants begin to flower, you can determine the sex of the plant by looking at the shape of the flowers. Male flowers are sparse, with smaller clusters of facing stamen that look like tiny balls on a thin stem. Female flowers have thicker clusters of white hairs (pistils) that look like miniature carrots grouped together.

Examine the Stalk

To identify a male cannabis plant, examine the stalk. Male plants have smaller stalks that are thinner and weaker-looking than those of female plants. The flowers of male plants are also typically smaller than those of female plants.

In addition, male cannabis plants typically flower earlier than female plants. If you are growing cannabis for purposes of producing buds (the flowers that contain the active ingredient THC), you will want to remove male plants from your grow room as soon as you can identify them.

If you are growing cannabis for other purposes (such as hemp production), you may not need to remove the males from your grow room. However, it is still a good idea to identify them so that you can track the progress of your crop.

How to Prevent Male Cannabis Plants from Pollinating Your Female Plants

Male cannabis plants can pollinate your female plants and ruin your crop. But how can you tell if a plant is male or female? And what can you do to prevent pollination?

Remove Male Plants as Soon as They Are Identified

As soon as you identify a male plant in your crop, remove it immediately. Male plants will start to release pollen when they are about 6-8 weeks old, which is around the time that most growers are getting ready to harvest their female plants. If you wait too long to remove the male plants, they will pollinate your females and ruin your crop.

The easiest way to remove male plants is to pull them up by the roots and dispose of them in a plastic bag. You can also cut them down at the stem, but be careful not to damage the nearby female plants. If you have a large number of male plants, you may want to consider using a tarp or something similar to contain them while you dispose of them.

Once you have removed all of the male plants from your grow room, make sure to keep an eye out for any new ones that may pop up. Male cannabis plants are often harder to spot than females, so it’s important to be diligent in your search.

Isolate Your Plants

The best way to prevent your female cannabis plants from being pollinated by male plants is to isolate them. This can be done by growing your plants indoors in separate rooms, or by growing them outdoors in separate areas that are far apart. If you are growing your plants indoors, you will need to use a fan to circulate the air so that the pollen from the males cannot reach the females. If you are growing your plants outdoors, you will need to isolate them by fencing off their area so that the males cannot get to them.

Use a Filter

You can use a physical filter to keep male pollen from reaching your female plants. This is especially effective if you grow your cannabis indoors. Polyester stretched over vents or spaces where air flows will prevent pollen from getting through while still allowing air to circulate. This method is not foolproof, however, as cannabis pollen is very light and can float for long distances.
